11.2.1.16 Read-Sector(s) - 20H or 21H
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of
0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When
this command is issued and after each sector of data (except the last one) has been read by the host,
the ATA Flash Disk Controller sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and
generates an interrupt. The host then reads the 512 Bytes of data from the buffer.
At command completion, the Command Block registers contain the cylinder, head and sector number of
the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The
Command Block registers contain the cylinder, head, and sector number of the sector where the error
occurred. The flawed data is pending in the sector buffer.
11.2.1.17 Read-Verify-Sector(s) - 40H or 41H
This command is identical to the Read-Sectors command, except that DRQ is never set and no data is
transferred to the host. When the command is accepted, the ATA Flash Disk Controller sets BSY.
When the requested sectors have been verified, the ATA Flash Disk Controller clears BSY and
generates an interrupt. Upon command completion, the Command Block registers contain the cylinder,
head, and sector number of the last sector verified.
If an error occurs, the verify terminates at the sector where the error occurs. The Command Block
registers contain the cylinder, head and sector number of the sector where the error occurred. The
Sector Count register contains the number of sectors not yet verified.
